Should I replace my batteries?
My two 6V Interstate batteries have been doing very well. They were installed by the dealer before we took delivery of our new X19H in June of 2011. Never had any issues with them, but wondering now ...

My 2010 trailer has the original GC2's, SG is still very close to new.
cycles, in the 300+ range, about half of them down to 25% SOC (75%DOD), A good GC2 is rated for 500+ cycles to 25% SOC.
Previously I ran a set of GC2's for 12 years with again 300+ deep discharges,then passed them to daughters In-laws who ran them 3 more years many discharges to 50% or less SOC before he replaced them.
My advice, charge the up, measure SG compare to what it should be new.
Also, load testing on GC2's will often give erroneous results. GC2 have high internal resistance so if you load test to the same load critera as a 12V starting battery it may show up as bad even on a well conditioned new battery.
